There is lot of talk about the ITIL Management certification along with PMP programs. I am thinking on doing Service and project management courses. Is the ITIL certification worth it? Collaboration.There is something to be said for the feeling Spark! Pro series – 15th July 2022 Spiceworks Originals.If we go back almost 100 years ago to July 15, 1928, it is the day that the ENIGMA machine encodes its first message. Snap!

Would you do this? IT & Tech Careersģ weeks ago I approached management and told them that I could achieve I'd also like to know why a relatively small rate of multicast packets (about 2Mbps, or less) is able to cause trouble on a 100Mbps network, or for that matter why multicast packets are appearing in a network segment where there are no subscribers (we have no IPv6 routers). It's likely that updating the Intel driver fixed the problem, but I'd still like to better understand why a low-level driver appears to be sending application-layer packets. However, I can't find that file on one of the problem computers. I have read that Bonjour for Windows is often installed with iTunes, and installs a program mDNSResponder.exe. I am not sure if these particular packets are necessarily associated with Bonjour, but it's possible. If Bonjour is running, then sometimes one can use avahi-resolve-address and avahi-resolve-host-name -4 on Linux to map the IPv6 link-local address to a local name and thence back to an IPv4 address and find the machines that way. The last 3 octets in the source address, 63:1e:cf, map to the last 3 octets of the MAC address, which with a bit of luck can be found in DHCP logs or router ARP tables. IP6 fe80::223:24ff:fe63:1ecf > ff02::2: HBH ICMP6, multicast listener reportmax resp delay: 0 addr: ff02::fb That does not excuse the volume of requests, of course.Į.g. That suggests that it wishes to become an mDNS querier per. As I understand it, the machine is telling any IPv6 routers that it wishes to be sent packets addressed to FF02::FB. I note that the packets seem to be a MLD request per. but it is not yet rolled out to Lenovo's site and has to be installed manually. The 12.11.96 driver from Intel appears to have solved the problem. But when I re-enabled the ports, the flood did not immediately return. Hard to diagnose - we had 3 machines sending packets, disabled the switch ports for two of them (disconnecting the machines), and the flood stopped from all 3. We had originally driver version 12.6.47, then upgraded to 12.8.33 and the flood returned. We have also seen this, from Lenovo machines with the Intel I217-LM and I217-V chips running Windows 7 and 8.
